I have been trying it for weeks but no luck. what i have done so far is created two accounts on developer site then with buy business account i created donate button whose code is 

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_donations">
<input type="hidden" name="business" value="6DHWKYCKBGXFS">
